My brain’s stuck again

I have portions of 2 songs stuck in my head
on some kind of endless loop

the first song is sung by
Vanessa Williams
and is called
“Save the Best for Last”

lovely and melodious
romantic song

the second song is done by
Akon featuring Eminem
and is called
“Smack That”

no so much with the lovely and melodious
and not so freaking romantic

but in my head the loop is:

“Just when I thought our chance had passed
You go and save the best for last”….
“smack that, all on the floor,
smack that, give me some more,
smack that, ’till you get sore
smack that, oooh”
“Just when I thought our chance had passed
You go and save the best for last”….
“smack that, all on the floor,
smack that, give me some more,
smack that, ’till you get sore
smack that, oooh”
“Just when I thought our chance had passed
You go and save the best for last”….
“smack that, all on the floor,
smack that, give me some more,
smack that, ’till you get sore
smack that, oooh”

Help me!
I’ve tried “In a Gadda da vida”
but even that ain’t helping this time
